A boy at school will just go out of his way to wind up my son every opportunity he gets. I had a word with the school and I changed my son's after school groups so he only had the school day to deal with him. The staff agreed that for months this boy would not leave my son alone and they would help to keep him away so my son had the freedom to play with who he wanted rather than being trapped by him.
One day at pick up my son had clearly had enough and snapped. My son got majority of the blame even after they said that they'd keep them apart and my son had been a victim of this boys almost jealous behavior. My son was falsely accused of being malicious when he'd actually put up with this behavior for 4 months without any retaliation.
However the Mum has been told numerous times her son needs to work on how he interacts with other people. She is constantly saying there's nothing wrong with her son's behavior. If the parent think the sun shines out of their child, how do you expect any change?,
